Dang Frank, I got your e-mail but I liked to have never found the agricultural forum.
I don't see anything special about the hog....except she'd look better on a breakfast plate. And the hogs we raised to eat only got table scraps. When they got larger and needed more food, some dry corn still on the cob. If we were raising some to sell, then they got store bought feed and dry corn on the cob out of the barn.
About that DUmb farmer, I'll put his well rounded knowledge of just about anything and everything up against a DUmmie with a PhD any day. The DUmmies, the smartest people in the world, would and will die from a multitude of causes when the SHTF...the DUmb old farmer will still be plodding right along.
TOTAL change of subject here. I hope somewhere, somehow, all the acquired knowledge of the world is stored in written form on paper or some other solid, readable, material, not computer tapes/disc/etc.. I would hate to think that in the end all practical knowledge such as simple farming with animals was lost because of the sudden demise of the electrical/computer age. There is already a lot of things my ancestors did to survive that is no longer used and it is long forgotten why or how they did it.
While we no longer "do it that way", it should be remembered how and why it was once done that way. We may have to go back to "the good old days" some day.
